Zhao Douan, in his past life, once came across a psychological phenomenon called the "Shanlu Zude Complex," named after the protagonist of "One Thousand and One Nights":
The Emperor summoned a young girl to his palace every night, only to kill her the following day.
To stop the killings, the Prime Minister's daughter, Shanlu Zude, voluntarily entered the palace. She told the Emperor a story every night, pausing at a critical juncture, and thus, the Emperor, eager to hear what came next, could only spare her life.
The next night, she would continue the story, pausing again... This went on for one thousand and one nights, eventually moving the Emperor to abandon the slaughter.
At this moment, Zhao Douan adopted the same strategy.
Considering that every cultivator dreams of becoming immortal, and choosing lengthy epics where obvious allusions like Journey to the West were inappropriate, he ultimately picked this one.
